Or you could turn your existing computer keyboard into a bluetooth keyboard for other peripheral devices for a fraction of the cost: http://www.eyalw.com/1keyboard
What's special about this Logitech keyboard is the switch to select the pairing with 3 devices so you don't have to pair and repair all the time to use the device with your phone and then your tablet and computer.
Same with 1keyboard - it does not need re-pairing. Assign a shortcut once to any device you want to switch between devices you want to send to and it's just as convenient and fast as that dial-switch of the Logitech should be.
I'm using 1Keyboard both with a Moto G and iPad mini Retina on a MBP 15'' Retina.
Yes! And also you can take it with you to take notes efficiently with your phone/tablet at school/conference! One keyboard for all you devices, so you don't have to buy multiple ones or get used to each keyboard. This is brilliant! All of this just with a switch, without any re-pairing!
>> You don't have to own a Mac to own an Apple keyboard - they're compatible with Windows, OSX and many flavors of nix
On the surface, that's true, but there can be little annoyances related to function key behavior, etc. on non-Mac OSes. Apple provides a Windows driver, but they don't appear to offer the keyboard configurator in Boot Camp to non-Mac owners.
